< cpp‎ | iterator‎ | insert iterator

insert_iterator( Container& c, typename Container::iterator i ); |  | (until C++20)
constexpr insert_iterator( Container& c, ranges::iterator_t<Container> i ); |  | (since C++20)

Initializes the underlying pointer to the container to std::addressof(c) and the underlying iterator to i.

### Parameters

c | - | container to initialize the inserter with
i | - | iterator to initialize the inserter with

### Defect reports

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

DR | Applied to | Behavior as published | Correct behavior
--- | --- | --- | ---
LWG 561 | C++98 | the type of i was independent of `Container` | it is the iterator type of `Container`
P2325R3 | C++20 | default constructor was provided as C++20 iterators must be `default_initializable` | removed along with the requirement
